You are making a point that uncontrolled railway crossings should be banned, correct.

Though what you don’t get is the concept of inertia at the train’s scale. You can’t just say “mass cancels out”. The specific energy to stop is the same per given amount of mass, however the amount of mass is not in the same league. Not to mention the CoF differentials between rubber/asphalt to steel/steel.

I agree that the lower coefficient of friction of steel on steel leads to less favorable maximum speeds for trains when applying the otherwise uncontroversial standard of possibly needing to stop at an uncontrolled crossing. I don't see what the amount of mass has to do with anything though. Like we don't condone SUVs or tractor-trailers ignoring red lights just because they're heavier and require more fuel to get back up to speed.

I'd say the problem with simply saying that uncontrolled railway crossings should be banned is that railroads will understandably say that it will take time to comply, and then stonewall for decades because of funding/whatever. Whereas the standard of liability can be changed atomically after some notice period, and if the railroads haven't upgraded their crossings to be able to maintain the speeds they'd like, that's on them.

Also the framing is different. Prohibiting certain types of crossings is creating new regulation, whereas removing the unjust liability shield is fixing traditional corruption.
